MUSIC-LEAF CLIP.

Specification of Letters Patent.

Application filed April 1, 1919. Serial No. 286,810.

To all whom it may concern: 7

Be it known that I, PETER'VAN VALKEN- nono, citizen of the Dominion ofCanada, residing at Otterville, in the Province of Ontario and Dominionof Canada, have invented certain new" and useful Improvements inMusic-Leaf Clips, of which the following is. a specification.

This invention has as its primary object to provide a novel form of clipfor attachment to music leaves to serve as a convenient means wherebythe leaves may be turned backwardly or forwardly.

' Another object of the invention is to provide a clip for the purposestated embodying two tabs extending generally in opposite directions andatsuch an angle that they will assume the most convenient position forbeing grasped in the act of turning the leaves both backwardly andforwardly.

Another object of the invention is to so construct the clip that thesame may be readily and quickly applied to and removed from a music leafand readily adjusted to any point along the margin of the leaf.

. A further object of the invention is to provide a clip so constructedthat its attachment to and detachment from a music leaf will not in anyway mutilate the leaf.

The invention has as a further object to so construct the clip that thesame will be light in weight and will, therefore, not cause the leaf towhich it is attached to sag.

In the accompanying drawings:

Figure 1 is a perspective view illustrating the application of theinvention.

Fig. 2 is a top plan view of one form of the clip applied to a musicleaf.

Fig. 3 is-a side elevation of the clip shown in Fig. 2. i v

Fig. 4l'is a view similar to Fig. 2, illustrating a modified form ofclip.

Fig. 5 is a view similar to, Fig. 2, illustrating a further modifiedform vention.

Fig. 6 is a perspective view of one of the jaws of the clip shown inFig. 5.

Fig. 7 is a vieu similar to Fig. 5 illustrating another form of theinvention.

In that form of the invention shown in Figs. 2 and 3 of the drawings,the clip comprises two counterpart jaw portions indiof the incated ingeneral by the numeral 1 and each including a shank 2 and a body 3having a transverse flattened lip portion 4. A spring '5 in the form ofa longitudinally split cylinder is provided with openings 6 receivingthe shank portions 2 of the clip jaws l, the

edges of the cylinder at its open side bearing againstthe outer sides ofthe lip' por-- tions 4c of the said jaws whereby to yield- "ably holdthese portions in mutual contact,

it being understood that the spring serves not only to hold the jawsclosed but also to 'hold the jaws in assembled relation and that thejaws may be opened by pressing together the ends of their shank portions2. As in the respects mentioned this clip is of a well known type, themanner of applying it to a leaf will be readily understood.

In carrying out the present invention the shank portion 20f each clipjaw is formed with longitudinal slits or incisions 7 resulting in afinger 8 which extends generally longitudinally of the respective shank2 but is sprung outwardly from the shank as shown in Fig. 2 of thedrawings. The numeral 9 indicates two finger tabs, one for each of theclip jaws, and these tabs may be formed from paper, light sheet metal,cloth, or any other material or combination of materials found suitablefor the purpose, although preferably flexible to a greater or lessdegree. Each finger tab 9 is formed with an opening 10, and a shankportion 11 of each finger tab is fitted frictionally be tween the outerface of the respective shank portion 2 and the finger 8, as clearlyshown in Fig. 2 of the drawings, the end of the finger extending throughthe opening 10 and being bent slightly outwardly as at 12 so as toprevent disengagement of the finger tab from the said finger.

In that form of the invention shown in Fig. 4 of the drawings, theconstruction is practically identical with the construction justdescribed and shown in Figs. 2 and 3 with the exception that in thismodified form the lip portions 4 of the jaws are each formed with aseries of teeth 13 adapting the aws to more securely engage the musicleaf to which the clip is applied.

In that form of the invention shown in Patented July 20, 1920.
